This property links together a series of LayoutRect elements. If the value of the nextRect attribute is not a valid LayoutRect element, the onlayoutcomplete event will be fired with the contentOverflow property set to true. Typically, the LAYOUTRECT element is created in the event-handling script invoked by the onlayoutcomplete event. See the LAYOUTRECT reference page for an example.
